Just finished this up to upgrade a Grohmann #4 Survival Knife (or similiar size). Hand carved. Edges and polished and sealed with a wax compound. Initials are Photoshop swirled for privacy.
Eric, the sheath is fabulous in every way. Being left handed has led to my making left hand sheaths, however, with so many right handed preference outdoorsmen in the family, I have been working on an ambidextrous sheath not unlike what you have there, however with a more rounded bottom edge. One question, however: Does pressure alone keep the Grohman or similar knife in place or is there any wet forming involved.
Wishalot. I never wet form them. With the thin "pancake" construction and welt construction, the front and back almost acts like a spring. When the knife is inserted, the top actually gets drawn together as the center of the sheath is expanded by the knife handle. When the knife is removed the top springs back a bit. I always use high quality, tight grained, 8-9 oz leather to make them (no bellies or cheaper cuts).
